Oracle Archive Logs
Oracle Database Tips by Donald Burleson


I want to clone a production 9i database to test database on Sun box (without RMAN - don't ask ). No problem with editing control file, commenting out RECOVER DATABASE etc.

However, the production DB runs with UNDO='AUTO' and when I try to open the 'new' test database Oracle insists I need to apply archive logs to recover.

Would I be correct in thinking that I could:

  • temporarily create a rollback segment in the production db before I copy the datafiles

  • edit the controlfile script to UNDO_MANAGEMENT=MANUAL

  • edit the new pfile to ROLLBACK_SEGMENTS='rbs1'

  • create new controlfiles

  • open database with RESETLOGS

Many thanks.

Ok, I am not sure I understand your complete issue, why not just copy the archive logs (or the online redo logs) across and apply them, then do a cancel and open resetlogs? Why all the mucking with rollback/undo segments?
